While this makes them somewhat unique in the animal world, as only three animals are now known to dance by verifiable proofs, what struck me more was that this was the first time YouTube had helped make a new scientific understanding. Given the explosive growth of uploading videos and people watching them, what other new understandings and popular misconceptions will be proven or disproved due to this emerging media?"
